  • Towable nonconductive pipe adapter for a sprinkler having laterally extending surfaces
    Patent number: 5511826
    Abstract: Mechanically locking sprinkler fittings are provided by this invention for making a fluid connection between irrigation pipes. The sprinkler fittings contain a tubular fitting member having first and second open ends for mating with a pair of irrigation pipes. The tubular fitting member contains a laterally facing orifice for receiving a sprinkler riser and an annular recess located along its surface which corresponds with a mating annular recess on at least a first of the irrigation pipes to form an annular cavity. The fitting also includes a flexible spline inserted into the annular cavity to form a mechanical lock between the first pipe and the tubular fitting member. The sprinkler fittings of this invention are convenient to use, and can be made of lightweight polymeric materials.
